Aetherium NeoForge

NeoForge build of Aetherium: own terrain renderer, animated video settings, frame pacing, culling, dynamic lights, zoom. 1.20.4 to 26.3.

Aetherium is a client-side performance and video settings mod. This project is the **NeoForge** build. It needs nothing else installed: no extra library or API mod.

 

It replaces the vanilla Video Settings screen with its own animated screen, and adds frame-rate features that work together with the vanilla renderer.

 

## Features

 

**Aetherium terrain renderer** (on by default)

- Skips the faces of each chunk section that point away from the camera, so the GPU draws less terrain.

- Never issues more draw calls than vanilla.

- If anything goes wrong, it switches back to vanilla rendering by itself instead of crashing.

 

**Performance**

- Entity occlusion culling: mobs and block entities hidden behind terrain are not drawn.

- Smart chunk culling: chunk sections fully inside the distance fog are not drawn or rebuilt.

- Smooth chunk loading, worker-thread sizing and a block-entity render distance.

- Even frame pacing with a max framerate set, for steadier frame times.

- Fast particles, visible-only animated textures and fast mob models (on the Minecraft versions that support them).

 

**Video settings screen**

- Animated, tabbed screen: General, Quality, Performance, Backend, Effects and Android.

- Light and dark theme, a draggable scrollbar, touch scrolling and interface sounds.

- Hover over any option to see what it does.

 

**Extras**

- Dynamic lights from held and dropped light sources.

- Zoom with smooth animation, scroll-to-zoom and rebindable Zoom / Zoom In / Zoom Out keys.

- Freelook, plus fog, sky and per-type particle controls.

 

## Compatibility

- **Minecraft:** 1.20.4, 1.20.6, 1.21 to 1.21.11, 26.1, 26.2 and 26.3. Download the file for your exact Minecraft version.

- **Loader:** NeoForge.

- **Client only:** not needed on servers. You can join any server with it.

- **Graphics:** targets OpenGL 3.0, so it also runs on older GPUs and on Android launchers.

- Versions 1.21.5 and newer are marked Beta because they have had less device testing.
